Jenelle Evans isn't happy. The Teen Mom 2 star recently got into a Twitter war with Kailyn Lowry over allegations that she's been drinking and smoking throughout her pregnancy. The tweets have now been deleted by both girls, but Jenelle apparently ended the argument by tweeting, "#TeenMom2 is about to be cancelled altogether cuz I’m about to quit #Dunzo."

Whoa.

Although there's currently no trace of the fighting words by either girl, Kailyn did leave this on her Twitter page:

My fault for the tweets. Should have texted Jenelle instead of going on here. Definitely wasn't thinking.

Things must have gotten heated between Jenelle and Kailyn to make Jenelle threaten quitting -- even though, let's get real here, people, we all know there's no way Jenelle would ever quit MTV. She loves being famous way too much. Also, who's to say MTV would cancel the show if Jenelle left?

Anyway, glad to see the girls squashed their issues, but I'd be lying if I said I wasn't super curious about the words that were exchanged. If there ever were two different types of mothers, it's Jenelle and Kailyn. I bet their claws came out.
